# love meter challenges
|
||||
|
||||
create a love meter with the BBC micro:bit #docs
|
||||
|
||||
## Before we get started
|
||||
|
||||
Complete the following guided tutorial:
|
||||
|
||||
* [tutorial](/microbit/lessons/love-meter/tutorial)
|
||||
|
||||
At the end of the tutorial, click `keep editing`. Your code should look like this:
|
||||
|
||||
```
|
||||
input.onPinPressed("P0", () => {
|
||||
let x = Math.random(11)
|
||||
basic.showNumber(x, 150)
|
||||
})
|
||||
```
|
||||
|
||||
### Challenge 1
|
||||
|
||||
Add a pause of 3000 milliseconds (3 seconds) after showing the number so that the number won't immediately disappear in the next challenge.
|
||||
|
||||
```
|
||||
input.onPinPressed("P0", () => {
|
||||
let x1 = Math.random(11)
|
||||
basic.showNumber(x1, 150)
|
||||
basic.pause(3000) // ***
|
||||
})
|
||||
```
|
||||
|
||||
### Challenge 2
|
||||
|
||||
If the rating **x** is between ``0`` and ``3`` (strictly less than ``4``), display the text "HORRIBLE!".
|
||||
|
||||
```
|
||||
input.onPinPressed("P0", () => {
|
||||
let x2 = Math.random(11)
|
||||
basic.showNumber(x2, 150)
|
||||
basic.pause(3000)
|
||||
if (x2 < 4) {
|
||||
basic.showString("HORRIBLE!", 150) // ***
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
### Challenge 3
|
||||
|
||||
### @video td/videos/love-meter-3
|
||||
|
||||
If the rating is between 4 and 7, display the text "MEDIOCRE!" **else** display the text "MATCHED!"
|
||||
|
||||
```
|
||||
input.onPinPressed("P0", () => {
|
||||
let x3 = Math.random(11)
|
||||
basic.showNumber(x3, 150)
|
||||
basic.pause(3000)
|
||||
if (x3 < 4) {
|
||||
basic.showString("HORRIBLE!", 150) // ***
|
||||
} else if (x3 < 8) {
|
||||
basic.showString("MEDIOCRE!", 150) // ***
|
||||
}
|
||||
else {
|
||||
basic.showString("MATCHED!", 150) // ***
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
### Challenge 4
|
||||
|
||||
Use `basic->plot image` or `basic->show animation` to display images and animations instead of text for each case.
